Found two of these handsome little guys under bark of oak log.

Moved from Prothalpia.

This beetle also has
a longer non-arcuate pronotum with a slight flare out at its base and the antennae seem to be uniform in color, both of which traits augur in favor of Hypulus simulator (=Hypulus trifasciatus). Since dorsal marking also are a far closer match, I am moving this to Hypulus simulator, which is on the UNH checklist for New Hampshire beetles.

Prothalpia undata, Family Melandryidae
Specimens of Prothalpia undata LeConte, Family Melandryidae. Never common, but found under bark without too much trouble.

Don, this species may be Hypu
Don, this species may be Hypulus simulator rather than P. undata. They are similarly colored, but P. undata has a zigzag basal marking on the elytra rather than the longitudinal streak. H. simulator also has very large basal depressions on the pronotum, half the pronotal length or more.

Larry, thanks. Both species are nicely sorted under the respectively wrong names in the collection. I must admit, I did it.

No Web pix
Thanks Larry. I googled you and found credentials, but the only photos I was able to google up were the four on this page :-( Next time I encounter this species I will be able to get some better pix of it.

Check images at MCZ type database; Hypulus trifasciatus Melsh is a synonym of H. simulator, and Prothalpia undata holotype.

That cinches it for me.
See other comment above.

Thank you Don!
I wondered how long it would take to get that one IDed. What do you think of the site?
